SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 616,949, dated January3, 1899. Application filed September 25, 1896. Serial No. 606,963. (Nomodel.)

To all whom it may concern:

Be it known that I, PORTER MARSHALL, a

, citizen of the United States, residing at Fair Play, in the county ofPolk and State of Mis- Improvements in Sash-Holders; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in sash-fasteners of that classin which the fastener is fitted to the 'jamb of the Window frame orcasing in operative relation to the sash which it is desired shall besustained in either of several positions within the win- (low-frame.

The object that I have in view is to provide an improved sash-fastenerin which the locking parts are housed or concealed wholly within thejamb and the sash, so that access may not be obtained thereto byevil-disposed persons.

In my invention the fastener isoperated solely by the vertical movementof the sash with which the fastener is combined, and to provide forthrowing the fastener out of looking relation to the sash the former isconstructed to be acted on by the sash to force it back within itsrecess in the frame-jainb by a slight lifting movement of the sashitself. have locking engagement with the sash for the purpose of holdingthe latter securely and steadily in either of its raised positionswithin the casing or frame.

To these ends the invention consists in the peculiar construction andarrangement of parts, which will be hereinafter fully described andclaimed.

In the accompanying drawings, Figure 1 is a side elevation of awindow-frame and its sashes, illustrating my improved fastener appliedthereto. Fig. 2 is an enlarged vertical sectional elevation through apart of the frame-jamb, showing my improved fastener fitted thereto andillustrating a part of the sash by dotted lines. Fig. 3 is an edge viewof one of the sashes, illustrating the perforated face-plate applied tothe sash and adapted to The fastener is also constructed to be used inconnection with my improved fastener. 1

Like letters of reference denote like and corresponding parts in eachfigure of the drawings.

A designates an ordinary frame or casing of a window, and B is a recessformed in one.

of the jambs of said frame or casing. Ihis recess may be lined by ametallic casing, as shown by Fig. 2; but this is not essential to myinvention. The edge of the sash-stile adjacent to the recess in thecasing-jamb is provided with a plurality or series of notches orrecesses spaced vertically at suitable distances from each other, and tothis edge of the sash-stile is rigidly secured in any suitable manner ametallic face-plate E, which is adapted to ride against the face of thejamb opposed thereto. This face-plate constitutes a wearplate to takethe wear from the sash-stile incident to the stile riding against thejamb of the window-casing, and in said metallic face-plate is formedaseries of slots or openings 6, which are coincident with the notches inthe stile of the sash.

My improvement resides in the peculiar formation of an automaticlocking-dog G. This locking-dog consists of a single piece of metalhaving a narrow elongated shank, which is tapered or flared from itspivoted end toward its free end, thus providing at the free end of thedog a surplusage of metal, which overbalances the dog and causes itsfree end to project or extend normally outward and beyond the verticalface of the frame-jamb. The outer edge of the enlarged head formed bythe tapering dog has an inclination or curvature forming abearing-surface in the path of the perforated metallic wear-plate, andthis bearing-surface forms one of the essential features of my improvedfastener, because the wear-plate is adapted to ride against said edge ofthe dog for the purpose of throwing the latter backwardly into itsrecess B when the sash is lifted quickly, thereby effecting theautomatic disengagement of the fastener from the sash to permit thelatter to be raised or lowered within the casing or frame A.

The head of my improved locking-dog G is furthermore provided with abeveled or inclined face F, which extends at an angle from the curved orinclined bearing edge just described, and this inclined or beveled faceF meets or joins a shoulder 0 provided in the enlarged head of thelocking-dog, such shoulder and the inclined edge F forming a notch atthe free end and on the upper edge of the headed dog and above theinclined or curved bearing edge of said dog.

The locking-dog G has its shank pivoted within a boxing or casing fittedin the recess B by means of a transverse pivot pin or screw D, and saidlocking-dog is thus arranged within the casing to have its weightedenlarged upper end normally projected beyond the vertical face of thejamb in which the dog is mounted. The casing or boxing in which thelocking-dog is housed is open at its side near the sash-stile, as shownby Fig. 2, and the outward movement of the gravity locking-dog islimited by means of a stop-pin H, which is fixed in the recess B abovethe pivot D and below the enlarged protruding end or head of thelocking-dog.

In the practical service of my improved sash-fastener the locking-doghas its headed and notched end extended into one of the openings e and arecess of the sash, and the notch of said dog fits against the upperedge formed by one of the openings e in the metallic face-plate E. Undernormal conditions the sash is free to be lifted, and during the raisingmovement of the sash the lower edge of the opening 6 in the face-plate Ebears against the inclined or curved bearing edge of the lockingdog,thus impelling the latter inwardly into its recess Bin the jamb. Thenthe sash has been raised the desired distance and one of the notches andopenings e arrive opposite to the notched headed end of the gravity-dog,the latter drops automatically into engagement with the sash, becausethe notch of the dog fits against the upper edge of the opening 2 in themetallic wear-plate. To

lower the sash, it is necessaryto lift the same quickly for a shortdistance and thereby bring the lower edge of one opening 6 against thebeveled or curved bearing edge of the automatic dog sufficiently toforce the latter inwardly into its recess, after which the sash shouldbe lowered quickly to prevent the notched end of the dog from havingengagement with the apertured face-plate E.

From the foregoing description, taken in connection with the drawings,it will be observed that I have provided an improved fastener which iswholly automatic in its operation, and that the disengagement of thelock ing-dog from the fastener is effected by proper adjustment of thesash itself. The described construction wholly obviates the provision ofmeans for the manual adjustment of the locking-dog, and said dog iswholly housed or concealed within the jamb of the window-casing and thevertical stile of the sash, so that access cannot be obtained theretofor throwing it out of engagement with the sash.

My improvement is distinguished from prior sash-fasteners of that classwhich are seated in the jamb of the window-casing by reason of the factthat the fastener is wholly automatic in its operation, whereas priorfasteners have been provided with means for manually adjusting the sameinto and out of engagement with the sash.

Having thus described myinvention, what is claimed as new, and desiredto be secured by Letters Patent, is-

In a device of the class described, the combination with a window-frame,and a sash provided with notches, of aninclined gravitydog pivoted atits lower end to the windowframe and having its upper end enlarged andarranged to engage the notches of the sash, said dog being provided atits enlarged end with the inclined face F, and having a curved ridingedge below the latter, and provided, above the inclined face F, with anotch forming a shoulder adapted to support the sash, said inclined faceF and riding edge enabling the dog to be operated solely by themovements of the sash, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

PORTER MARSHALL.
